Transcript of Embedded versus Bluetooth - Evaluating the connectivity options for telematics
Finding the best connectivity solution to support your telematics business model...
Many vehicle manufacturers are currently planning which connectivity solutions to adopt for their next generation infotainment and navigation platforms. This choice is complicated by two factors; infotainment and connected navigation services have very different data requirements and usage profiles compared to more traditional safety and security services, while advances in the telecommunications industry have led to an increasing number of viable connectivity solutions to choose from.
This report assists manufacturers and suppliers caught up in this ‘connectivity conundrum’ by identifying and analysing the potential solutions for enabling telematics connectivity where the intelligence is retained in the embedded vehicle system (smartphone integration is excluded). An overview of each solution is supplemented by the positives and negatives of each approach. Considering the strengths and weaknesses of each solution, the report concludes with a balanced perspective on which are the most suitable connectivity options for premium and volume vehicle manufacturers – some of which may be surprising.

Learn what factors are preventing widespread adoption of some connectivity solutions in the car
Evaluating the connectivity options for telematics
Built-in: Embedded modem and SIM
Hybrid: Embedded modem, customer SIM
Brought-in: Bluetooth link to customer phone
Brought-in: Plug-in modem
Brought-in: Wired link to customer phone
Advantages DisadvantagesCommunications not reliant on external devices Relatively high system costs
Works ‘out of the box’ without user setup Risk that embedded modem may become obsolete
Suitable for all types of services (including security) Increased implementation time
No compatibility / interoperability / tethering issues For OEMs that cover the ongoing communications costs there is reduced flexibility in the business modelOEM can specify modem according to needs
Overview
Bluetooth SAP
Advantages DisadvantagesRobust comms channel (vehicle modem and antenna) BT SAP not fully supported even in newer phones
Ongoing communications charges passed to end user Cannot be used for security-related services
Greater flexibility for OEM business model Not a global solution (US market has SIM-less CDMA)
Improved battery life for user’s phone Limited cost saving compared to embedded solution
OEM does not have to build relationship with MNO Risk that embedded modem may become obsolete
Advantages DisadvantagesRobust comms channel (vehicle modem and antenna) Not suited for security-related services such as SVT
Ongoing communications charges passed to end user Not a global solution (US market has SIM-less CDMA)
Greater flexibility for OEM business model Limited cost saving compared to embedded solution
Reliable connection to SIM (not wireless link) Only realistic use scenario is for user to get an additional SIM card, but this is inconvenient and may be costlyOEM does not have to build relationship with MNO
SIM slot
Overview
Advantages DisadvantagesTCU cost reduced (no modem or SIM) Not suitable for security-related services
Ongoing communications charges passed to end user Comms reliant on quality & performance of device
Greater flexibility for OEM business model Antenna reception worse than embedded solution
Avoids Bluetooth profile implementation issues Modem likely to be OEM-specific with OEM software
Independent of phone; voice calls possible at same time Visually unattractive solution
Advantages DisadvantagesTCU cost reduced (no modem or SIM) Communications reliant on the user’s mobile phone
Ongoing communications charges passed to end user Not suitable for security-related services
Greater flexibility for OEM business model User may have to pay high charges for data use
Avoids Bluetooth profile implementation issues Potential connector longevity concerns
User’s phone can be charged whilst in use TCU software must interface with different mobiles
Overview
Advantages DisadvantagesBT HFP is widely supported; no MNO tethering issues Communications reliant on the user’s mobile phone
Use of DOV means users only charged for voice calls Data transfer very slow – unsuitable for some services
TCU cost reduced (no modem or SIM) Not suitable for security-related services
Ongoing communications charges passed to end user Bluetooth connections not as reliable as a wired link
Greater flexibility for OEM business model DOV likely to require proprietary tech (license fee?)
